Keylogger for the Android device!

The generation has changed a lot. People are much more aware than before. Nowadays it’s very hard to keep yourself safe and sound. I would like to use a keylogger to observe everything within one place. I have heard about keylogger which can be helpful for me to do. Besides, by using a keylogger I can easily track fraudulent activity. Can you please suggest me a good one?

Thank you!
